C. BACKREST INSTALLATION C

To install backrest, remove the nut, plastic saddle and bolt from the backrest tube. Place the backrest in the upright position and reinstall in the lower plate hole

(C). Backrest bolts should be tightened to 35 in-lbs. Avoid over-tightening as you may crush the backrest tubing.

D. BACK ANGLE ADJUSTMENT

Turn the eccentric bolt (D) on the backrest hinge plate to increase or decrease the back angle. The adjustment on each side must be exactly equal.

E. SEAT SLING ADJUSTMENT

Remove the screws retaining the left side seat sling. Readjust VELCRO® -style material to increase the ten- sion in the seat sling. Replace screws. If there is any difficulty in reattaching the screws, try using a probe to help line up the holes.

NOTE– Adjustment to rear seat height may also require caster angle adjustment. See Letter I.

G. CUSHION (OPTIONAL) INSTALLATION

Place cushion on seat sling with VELCRO® side down. The beveled edge of the cushion should be in front. Press firmly into place.

H. REAR AXLE

The most important adjustment on your Quickie wheel- chair is the position of the rear axle. The center of gravity and wheel camber are determined by the axle adjustment.

1. Center of Gravity Adjustment

You can adjust your center of gravity position by mov- ing the two axle plates (B) forward or rearward on the seat tube (C). Moving the axle plates forward shortens the wheelbase and lightens the front end, making your chair more maneuverable. Moving the axle plates rear- ward makes the chair more stable and less likely to tip over rearward.

NOTE– Changes to the center of gravity may affect the rear seat height (Letter F), toe-in/toe-out of the rear wheels (Section H-3) and the squareness of the casters (Letter I). If you change your center of gravity position, re-adjust these if necessary.

Before adjusting your wheelchair’s center of gravity, locate the additional saddles supplied with the chair. This hardware may be required depending on the over- lap position of the axle plates and back plates.
